Justin Bieber Prays with Kanye West and P. Diddy

On Instagram, pop superstar and self-confessing Christian Justin Bieber demonstrates his Christian faith. Recently, the heartthrob posted a picture of himself praying with hip-hop stars Kanye West and Sean "Puff Daddy" Combs. The picture shows the "Sorry" singer standing side-by-side with Kanye West and P. Diddy with their eyes closed in prayer. Bieber captioned the photo, "Uncle puff and Yeezy giving thanks to Jesus."

Bieber, who is currently on his "Purpose" tour, revealed he has experienced some spiritual fatigue over the past few weeks, and recently cancelled all of his scheduled meet-and-greet events with fans.

"Love u guys.. I'm going to be canceling my meet and greets. I enjoy meeting such incredible people but I end up feeling so drained and filled with so much of other people's spiritual energy that I end up so drained and unhappy ..." Bieber wrote in an Instagram post last week. "Want to make people smile and happy but not at my expense and I always leave feeling mentally and emotionally exhausted to the point of depression. ... The pressure of meeting people's expectations of what I'm supposed to be is so much for me to handle and a lot on my shoulders."

Besides Justin himself, his mother Patti Mallette has also been praying for him. Pattie Mallette, a committed Christian, hopes her son will have an encounter with God.

When Bieber celebrated his birthday recently, his mother sent him a birthday greeting via Twitter: "22 years ago I was 18 [years] old, pregnant & scared. But God. Lord encounter @justinbieber for his bday! Give him all I couldn't in Jesus name."

The relationship between Bieber and his mother got strained when he catapulted into the limelight and indulged in a life of heavy drinking, partying, and drugs. "I was distant because I was ashamed. I never wanted my mom to be disappointed in me and I knew she was," Bieber told Billboard last year. "We spent some time not talking, so it takes time to rebuild that trust. She's living in Hawaii now, so it's hard, but getting better."
